Description: Enables the tracing in the selected submodule in VLAN. A 32 bit integer is used to store the Tracing level in the specified module. Different Tracing Levels - BIT 0 - Initialisation and Shutdown Trace. BIT 1 - Management trace. BIT 2 - Data path trace. BIT 3 - Control Plane trace. BIT 4 - Packet Dump. BIT 5 - OS Resource trace. BIT 6 - All Failure trace (All failures including Packet Validation) BIT 7 - Buffer Trace.

Different submodule Tracing - BIT 16 - Tracing in VLAN module. BIT 17 - Tracing in VLAN Priority module. BIT 18 - Tracing in VLAN Redundancy module.

The remaining bits are reserved. The combination of levels and submodules are allowed i.e. Tracing can be allowed at all failure and data path level in All submodules by setting the BIT appropriately. For Example, setting the debug value to the following bit stream, 00000000000000010000000000000100 will enable data path trace prints in VLAN module. Multiple submodules and multiple levels can be combined by setting the corresponding bits. For Example, setting the debug value to the following bit stream, 00000000000000110000000000001100 will enable data path and control plane trace prints in VLAN and VLAN Priority modules.

Note : BIT0 is the least significant bit and BIT31 is the most significant bit.
